The invention relates to window regulators and has for one of itsobjects the provision of a simple construction of mounting for theirreversible drive mechanism and handle. Another object is to soconstruct the parts that one member forms the combined housing for theirreversible drive mechanism and the support for the escutcheon. Afurther object is to so construct-thismember that it may be cheaplymanufactured and it and the associated parts may be readily assembled.With these as well as other objects in view, the invention resides inthe novel features of construction and combinations and arrangements ofparts as more fully hereinafter set forth.

In the drawing y Figure 1 is an interior side elevation of a windowregulator embodying my invention;

Figures 2 and 3 are cross sections on the lines 2-2 and 3-3 of Figure 1;

Figures 4 and 5 are cross sections on the lines 4-4 and 5-5,respectively, of Figure'2.

As shown, the regulator embodying my in- I vention has the mountingplate 1, which is rigidly secured to an element, such as a lock board ofa motor vehicle. 2 is the lifter element of the window regulatorcomprising the lifter arm 3 and the gear segment 4, the lifter armhaving the pin 5 at its outer end for connection to the window and beingrigidly secured at its inner end to the gear segment. This lifterelement is pivotally mounted upon the mounting plate by means of thepivot 6, which is rigidly secured to the lifter element and is journaled in the mounting plate. 7 is the handle of the window regulatorand 8 is the irreversible drive mechanism between the handle and thelifter element for actuating the latter from the former. Theirreversible drive mechanism comprises the driving member 9 which is inthe nature of a shaft having at one end the diverging wings 10 and atthe other end the serrated portion 11 and intermediate these ends thecylindrical portion 12. 13 is the driven member of the irreversibledrive mechanism having the diametrically opposite fingers 14, one ofwhich is adapted to extend between the wings 10. This driven the portion22 member is journaled upon the spindle .15 which is rigidly secured tothe tongue .16 upon the mounting plate 1 and'eXt-ends axially into andforms a bearing for'the driving member 10. 17 is a pinionfsecured to androtatable with the driven member 13 and. meshing with-the: gear segment'4 for driving the latter upon actuation of theformer.

18 is the'resilient' coil spring ofthe irre versible drive mechanismencircling the wings 10 and the fingers 14 and arranged to normallyexpand against a stationary memher to frictionally lock the parts intheir various positions of rotative adjustment. This coilspring has theinturned ends 19 which are adapted to'extend between the wings 10 ofthe'driving member'andthe finger 14 of the driven member between thesewings, the. arrangement being such that uponrotation of the drivingmember in opposite directions 79 the wings are alternativelyengageable'with the inturned ends of the coil spring to con-. tract thesame and releas/ethe look, after: which the engaged inturned end isforced into contact with the finger between the 7 wings and the drivenmember isrotated.

To provide a simple construction for mounting the handle and forengaging the coil spring'when expanded or in looking position, there isthe drawn tubular sheet metal 39 member 20, which is formed with theannular flange 21 adapted to be rigidly secured to the mounting plate 1.This'tubular' member has for housing the irreversible drive mechanismand the portion 23 which is s5 internally threaded. Italso ha'sthestruclrout tongues 24 intermediate the portions 22 and 23 and extendingradially inward for abutting the cup-shaped washer 25 to position" thesame. The cylindrical flange of this washer is adapted to engage theadjacent end convolution of the coil springlS to hold the latter fromaxial movement away from the mounting plate, while the web of thiswasher forms a bearing for the cylindrical portion 12 of the drivingmember. The internally threaded portion 23 is adapted to detachablyengage the escutcheon 26, which forms abearing for the handle 7 and atthe same time con-,

ceals the portion of the lining'surrounding 1 the tubular member 20. Theescutcheon, which may be formed of one or more sections, threadedlyengages the internally threaded portion 23 and has the handle 7permanently rotatably secured thereto. The handle is provided with aserrated socket 27 for fitting the serrated end portion 11 of thedriving member 10.

What I claim as my invention is:

' 1. In a window regulator, the combination with irreversible drivemechanism including a coil spring, a handle for actuating said mechanismand a bearing member for said handle, of a tubular sheet metal membercommon to both said mechanism and bearing member for housing said coilspring and frictionally engaging the same when in locking position andfor detachably receiving said bearing member to support the same, saidtubular member having struck-out tongues for positioning said mechanism.

2. In a window regulatonthe combination with irreversible drivemechanism including a coil spring, a handle for actuating said mechanismand an escutcheon member, of a tubular sheet metal member having aportion for housing said spring and frictionally engaging the same whenexpanded, a second portion for detachably receiving said escutcheonmember to support the same and struckout tongues intermediate saidportions, and an abutment member within said tubular member andpositioned by said tongues for engaging an end convolution of said coilsprmg.

3. In a window regulator, the combination with irreversible drivemechanism, a handle for actuating said mechanism and a bearing memberfor said handle, of a sheet metal member having a portion for housingsaid mechanism and frictionally engaging the same, a'second portion fordetachably supporting said bearing member and struck-out tonguesintermediate said portions providing positioning means for saidmechanism.

4. In a window regulator, the combination with a mounting plate, ahandle, irreversible drive mechanism and a bearing for said handle, of atubular sheet metal member secured to said plate having a portion forhousing said mechanism and frictionally engaging the same, a secondportion detachably supporting said bearing member and struck-out tonguesintermediate said portions cooperating with said mounting plate toprovide positioning means for said drive mechanism.

In testimony whereof I afiix my signature.
